Brandon Weeden became the “old guy” in college football when he joined the Cowboys program in 2008. By 2010 he was the starter and had become one of the country’s top storylines alongside star receiver Justin Blackmon.

He passed for over 4,000 yards two years in row and ended his career with 75 passing touchdowns.

The Cowboys marched to 23 wins in two seasons with Weeden leading the offense.

Weeden finished his career with 9,260 passing yards and a 69.5 completion percentage.

No. 8: Collin Klein, Kansas State Wildcats

Kansas State was in the BCS title discussion for two seasons with Collin Klein leading the offense. The Wildcats looked to his leadership and tenacity to fuel a Big 12 title run in 2012.

Over the course of his four-year career, Klein passed for 4,724 yards and 30 touchdowns. He also rushed for 2,485 yards and 56 touchdowns.

His impact on the Kansas State program will be unforgettable, despite his lack of explosive passing numbers. Klein was a leader and took the offense on his back for two straight seasons, taking the Wildcats to a BCS bowl game in 2012, which happened to be Kansas State's first since 2003.

No. 6: Vince Young, Texas Longhorns

Winning national titles is the highest honor that a college football player can achieve. Winning the Heisman is a close second.

Vince Young knocked down one of those achievements while at Texas—he guided the Longhorns to the national title in 2005, but he finished second in the Heisman voting in 2005.

Some argue he should have walked away with the award thanks to his strong 2005 season. He finished the year with 3,036 passing yards and 26 passing touchdowns while also adding 1,050 rushing yards and 12 rushing TDs to his stat line.

He finished his Longhorns career with 6,040 passing yards, 3,127 rushing yards, 44 passing TDs and 37 rushing TDs. His career record as a starter was 30-2.

No. 4: Kliff Kingsbury, Texas Tech Red Raiders

Kingsbury was one of the first players to play in the Mike Leach adaptation of the “Air Raid” offense at Texas Tech.

He played in 43 games during his career and finished with a handful of records. He passed for 12,423 yards and 95 touchdowns as the Red Raiders quarterback. He is now the head coach for the Texas Tech program.

Despite being labeled as a system quarterback, Kingsbury was drafted by the New England Patriots in the sixth round during the 2003 draft.

No. 2: Robert Griffin III, Baylor Bears

Most people don’t look to Baylor when mentioning elite quarterbacks, but in 2011, the Bears produced one of the best the Big 12 has ever seen.

Robert Griffin III stole the country’s attention when he plowed through the conference to become the first Heisman winner in Baylor history. He finished the year with an astounding 189.5 passer rating while passing for 4,293 yards and 37 touchdowns.
